Edit "My Number" in Phone Application

So I just got a Blackberry Tour Unlocked, it was originally locked to bell, but now im running it on a Rogers Sim
and I had this same problem with my Storm, i tried the same thing I did with the storm on my tour but not luck
so what am I to do, I keep hearing something about MSL code
and no ##000000, its says invalid code, and I tried ##111111 but it says I have been locked out too many attempts is there a way to unlock it ? like when you lock yourself out of a computer?

either way how do change my number because when I type mynumber (like how your type Mypin) it shows the previous owners number, rather than mine, my number is fine under the Sim in the advanced options menu though
I have been all of google and no luck so now im desperate im posting for help, so any help would be greatly appreciated , please and thank you

I have a TELUS storm 2 9550, had the same problem with the my number, tried using the unicdma and hex tool but it is only for the older versions. I ended up getting "my number" changed, by going onto ebay and purchased a SPC/MSL # for 8$, tested and worked good..
